Crystalyte 100V 90A for brushless motorthis is a original 72V 35A Start immediate that i moded with 12 IRFB4110 Mosfet. I also replaced the large capacitor inside with lower ESR and larger capacity

Batteries

432 Sony 18650V (known as Konion).used in Makita, Bionx an, 3.75 Volt, Lithium-Ion2.21 Kilowatt-hour LiMnO2
I built this pack myself with engineering knowledge for thermal management and safety protections.
I used many used 18V 3Ah LXT power tools battery pack of Makita.
These cells are 1600mAh each and are mounted in 24s 18p groups.
The total pack give 100.8V fully charged and 24Ah.
can take 10C discharge

no need equalizing!!

System Voltage

101 Volts

Charger

Doctorbass DIY 1.0kW charger/BalancerI take 2h10 for full charge!

I built the 20A rate multi charger.
it is made of 12 DC-DC Artesyn converter that are adjusted to 4.2V and 20A current limit.. all DC-DC are powered by a Meanwell 48V 32A PFC power supply.
